This book had very beautiful lyrical writing, but I was confused most of the time, especially in the first 70 pages. It’s one of those books where they just drop you right into the middle of it and you kinda have to figure out what the heck is going on as you read. The premise is really intriguing, but I think it falls short in execution. I was having a really hard time envisioning what I was reading because of the lack of world building and descriptions. There were a lot of descriptions don’t get me wrong, but they were mostly metaphorical and sounded nice, but didn’t do much to help you picture what’s actually happening. I didn’t care all that much about the characters’ and their relationship. They were just kind of in love? and it was forbidden? The whole plot twist with the shadow was a little predictable. I did enjoy Red and Blue’s letters. I think that was a really good way to showcase the development of their relationship, I just wish we got a little more of that and a little more context in this complicated world. I also liked the the descriptions of their missions and the ramifications they had on the rest of time. Again, I wish we got more of that. Overall, this book is very quotable, but it was too much effort trying to understand what was happening for not a whole lot of reward.
